EViews.com

The error you are seeing is not a result of where EViews is installed but the location of the EViews temp directory. The directory C:\Users\John\AppData\ev_temp\TRAMO either does not exist or you do not have write permissions.

If you find you cannot create the directory or change the permissions, as a test create c:/temp on your computer, select in EViews Options->General Options->File Locations, and change the entry for Temp File Path to c:/temp.

I was also reminded by Gareth, it is possible your data is causing an error in TRAMO which would prevent the creation of seats.itr. To verify this is the case, try performing the same seasonal adjustment on several different series (if possible from a different workfile) and see if you get the same error. If all cases return the same error, then refer to my previous post. Otherwise contact support@eviews.com and include your workfile.

Many thanks, Jason.

It appears that the problem was indeed the data - it seems that Tramo does not like to have "NA"s in the data at the start of the sample (although it seems to work when the NAs are within the sample).
